Translation of Kindergärtner

The connecting flight to Phuket was fully booked, and the connection to Krabi had five empty seats. The problem was that the boarding began in ten minutes and I did not even have a ticket.
I have sent you the translation a few hours ago. I guess it has just arrived. That is very responsible of you. I will have a look at it immediately. If you want to address somebody formally in the singular, you must use 'usted'.
I'm also not interested in such things, but I had a classmate who recommended the book 'Mice and Men' and that's why I bought it. It is a very interesting book and tells about old times in the U.S.
